Abstract: Aspects relate to measuring downlink beam quality in the presence of self-interference when operating in a full duplex mode configured for concurrent transmission and reception within an overlapping bandwidth. A user equipment (UE) may communicate with a base station over one or more of a plurality of uplink beams and downlink beams. For each uplink beam, the UE may obtain beam quality measurements associated with each of the downlink beams to identify a set of usable downlink beams. The UE may further transmit a report to the base station indicating the set of usable downlink beams for at least one uplink beam.

Abstract: Techniques are provided for calibrating group delay for a low-tier UE by leveraging the relatively high accuracy of RTT positioning for a premium UE. This can enable online/in-field group delay calibration of low-tier UEs, allowing for low-tier UEs to be calibrated when needed. Depending on desired functionality, techniques for calibration may include the use of RTT measurements with a base station, or an RTT measurement between the low-tier UE and the premium UE.

Abstract: In an aspect, a serving BS of a UE measures ToAs of a DL-PRS from a non-serving base station of the UE and an UL-SRS-P from the UE. The serving BS transmits measurement information based on the ToA measurements of the DL-PRS and the UL-SRS-P to a position estimation entity. The position estimation entity determines a positioning estimate for the UE based in part upon the measurement information.

Abstract: A method for supporting radar operations may involve providing, from a radar server, one or more transmit beam parameters, over one or more wired or wireless interfaces, to a first wireless communications system Transmission Reception Point (TRP) for configuring a transmit beam for sending a transmit signal from the first wireless communications TRP. The method may further involve providing, from the radar server, one or more receive beam parameters, over one or more wired or wireless interfaces, to a second wireless communications system TRP for configuring a receive beam for receiving, at the second wireless communications system TRP, an echo signal from one or more targets as a reflection of the transmit signal. The first wireless communications system TRP and the second wireless communications system TRP may be part of a wireless communications system.

Abstract: A muting configuration for downlink positioning reference signals (PRS) is based on the slot type in which the PRS is transmitted. A slot type muting configuration mutes PRS if the PRS are transmitted in a full duplex slot, such as an in-band full duplex slot. If the PRS are transmitted in a sub-band full duplex slot, the PRS may be muted depending on whether the base station is capable of self-interference cancellation. The slot type muting configuration does not mute the PRS transmission in a half-duplex slot. The slot type muting configuration may be dynamic and may be provided to a user equipment (UE) in lower layer signaling to improve latency. The slot type muting configuration may be combined with other types of muting configurations, such as inter-instance muting, intra-instance muting, and intra-slot muting, e.g., using a logic function to combine the configurations.

Abstract: In an aspect, a UE determines a power consumption of the UE for a position estimation procedure based on a set of power consumption parameters associated with the UE, the set of power consumption parameters comprising one or more layer-specific parameters associated with a set of positioning frequency layers (PFL), a Positioning frequency layer processing capability of the UE, a positioning reference signal (PRS) resource processing capability of the UE, a PRS measurement type capability of the UE, a positioning session processing capability of the UE, or a combination thereof. The UE performs one or more positioning measurements associated with the position estimation procedure in accordance with the determined power consumption.

Abstract: Techniques are provided for time-domain processing of DL-PRS signals under certain conditions in which time-domain processing has a computational advantage over frequency-domain processing. Because of this, embodiments can provide positioning at a lower computational cost than positioning provided by traditional techniques utilizing only frequency-domain processing. This reduced computational cost can improve the battery life of mobile devices, ultimately resulting in a better user experience.

Abstract: Techniques are provided for utilizing positioning reference signals (PRS) in full duplex scenarios. An example method for wireless communication by a user equipment (UE) includes receiving a positioning reference signal in a time slot, wherein the positioning reference signal spans a first frequency bandwidth, transmitting a signal in a second frequency bandwidth during the time slot, wherein the second frequency bandwidth includes frequencies within the first frequency bandwidth, and processing the positioning reference signal received in the first frequency bandwidth excluding the frequencies in the second frequency bandwidth.

Abstract: Disclosed are techniques for wireless communication. In an aspect, a UE obtains measurement data associated with at least one PRS. The UE transmits, to a BS in a first L1 or L2 PSI report opportunity, a first PSI report indicative of a first set of measurement values associated with the at least one PRS based on the measurement data. The UE further transmits, to the BS in a second L1 or L2 PSI report opportunity that is subsequent to the first L1 or L2 PSI report opportunity, a second PSI report that is indicative of a second set of measurement values associated with the at least one PRS based on the measurement data, the second set of measurement values being refined from the first set of measurement values.
